UNITED STATES innate PATENT FFt APPLIANCE FOR CLEANING WINDOWS FROM THEINSIDE.

Application filed April 11, 1922. Serial No. 551,597.

To all whom it may concern:

Be it known that I, HIPPOLYTE M. CHIRON, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Appliances forCleaning Windows from the Inside, of which the following is aspecification.

This invention relates to window cleaners l and the main object is toprovide a device which is particularly adaptable for cleaning theexterior surface of a window pane, without endangering the person toinjury from falling out.

Another objectis to provide a device as described, designed in suchmanner as to be readily taken down and folded compactly to be stored ina relatively small space when not in use. Still another object isto-provide a device which is capable of bein moved from place to placein a window with the greatest ease, and effective and speedy.

These and other objects will become W apparent in the description belowin which similar characters of reference refer to like-named parts indrawing.

Referring briefly to the drawings, in which, Figure 1 illustrates awindow and 30 shows the device thereon in an extended position.

Figure 2 is a perspective view of the cleaner brush.

Figure 3 is a front elevational view of 35 the device, in extendedposition.

Figure 4 is a side elevational view of the same.

- Figure 5 is a top plan view thereof.

Describing the drawings in detail, the t0 numeral 1 represents a windowframe imbedded in a brick wall 2 and has a pair of sashes 3, and theusual type of windowsill 1. The window cleaning device rests upon thesurface of sill 4 and comprises a substantially rectangular platform 5provided with cutout end portions 6 to receive traction rolls 7, whichare rotatably mounted upon pins 8.

A reinforcing member 9 extending longi- 59 tudinally of the platform =5has a hinge 10 secured centrally thereon, the hinge having a guide beam11 kept in normal upright position by a wire stanchion 12.

- A lazy tongs 13 is guided in an upward direction adjacent to beam 11by having its pivot studs 14 engage a T slot 15 formed throughout thelength of the beam.

The upper ends of said lazy tongs 13 are hingedly connected by a hollowpin 16 while the lower separated ends 17 are rounded and provided withslots 18. Said ends 17 are capable of a transverse motion in a channelformed by the guide ridges 19.

Crossed levers 20 pivoted at 21 on the platform 5, have reduced ends 22which are engaged in the slots 18, and grip handles 23, provlded at theopposite ends have a spring 24 which normally urge or pull the outerends toward each other thereby extending or lengthening said lazy tongs.

The hollow stud at the upper end of the lazy tongs receive one end of aclosely wound spring 25 which hangs downwardly, its projecting lower endentering a sleeve lug 26 forming part of a rectangular frame 27. Saidframe has a hinged upper member 29 which is normally retained in theposition shown in Figure 2, by springs 30 The open edges of both theframe 27 and frame cover 29 are provided with sharp teeth 31 which biteinto a pad 28 composed of such material as'felt, rubber or sponge.

The rear end of platform 5 is supported by an additional roller 32capable of being swivelled and raised or lowered to suit theconstruction of the window sill.

In using the device the lower window sash 3 is opened a sufiicientdistance to allow the platform 5 to be placed on the sill with the beam11 located on the outside of the device is mounted upon the rotatablemembers 7 and 32, it; can be easily pulled to any position relative tothe width of the sill.

A pad 28 is placed in frame 27 and the lazy tongs 13 are extended andcollapsed by manipulation of the crossed levers 20, thus giving .avertical reciprocal motion to the cleaning pad'28 thereby cleaning thesurface of the window pane.

In preparing the device for storing the lazy tongs 13 are removed bysliding upwardly out of the "3 slot 15 and detaching one end of thestanchion 12 from the beam 11 will transversely over said platform, astanchion to ermit the latter to be rotated about its retaining saidbeam in upright position, inge and lie flat upon the platform 5. lazytongs guided in said EV-shaped slot, an I claim elongated frame securedto the upper con- 5 A Window cleaner comprising a rollernested ends ofthe tongs, a cleaner pad, and.
